Interpretive Summary: Both adults and larvae of the Asian longhorned beetle genus Anoplophora have been recently intercepted at ports in the United States, and it has been recently established in New York City. An aggressive eradication effort is being undertaken to control its spread. This beetle is a major pest of hardwood trees including maples and elms and has the potential to spread throughout the United States. Larvae of this beetle can easily be confused with native species of the genus Monochamus and this paper presents information that allows their identification. This information will be very useful for taxonomists and port identifiers, and others involved with monitoring exotic insect introductions.

Technical Abstract: An Asian longhorned beetle, Anoplophora glabripennis Motschulsky - native to eastern China (including Manchuria and the island of Hainan), Korea, and Japan - was discovered in late August 1996 attacking various hardwood trees in New York City. This represents the first known infestation of any member of the lamiine genus Anoplophora in North America. The mature larva is thoroughly described and important morphological attributes are illustrated with the use of color microphotographs. Furthermore, the larva of A. glabripennis is compared with larvae of the North American conifer-infesting genus Monochamus which are very similar.
